Patents by Inventor Andreas H. Trabesinger

Andreas H. Trabesinger has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Low field magnetic resonance imaging
    Patent number: 7750633
    Abstract: A method and system of magnetic resonance imaging does not need a large homogenous field to truncate a gradient field. Spatial information is encoded into the spin magnetization by allowing the magnetization to evolve in a non-truncated gradient field and inducing a set of 180 degree rotations prior to signal acquisition.
    Type: Grant
    Filed: July 21, 2005
    Date of Patent: July 6, 2010
    Assignee: The Regents of the University of California
    Inventors: Alexander Pines, Dimitrios Sakellariou, Carlos A. Meriles, Andreas H. Trabesinger

  • Squid detected NMR and MRI at ultralow fields
    Patent number: 7466132
    Abstract: Nuclear magnetic resonance (NMR) signals are detected in microtesla fields. Prepolarization in millitesla fields is followed by detection with an untuned dc superconducting quantum interference device (SQUID) magnetometer. Because the sensitivity of the SQUID is frequency independent, both signal-to-noise ratio (SNR) and spectral resolution are enhanced by detecting the NMR signal in extremely low magnetic fields, where the NMR lines become very narrow even for grossly inhomogeneous measurement fields. MRI in ultralow magnetic field is based on the NMR at ultralow fields. Gradient magnetic fields are applied, and images are constructed from the detected NMR signals.
